71-528331-35S

Overview

The Amphenol Aerospace Operations part number 71-528331-35S is a circular MIL-DTL-38999 Series III connector receptacle. It features a size 35 shell with 35 socket contacts designed for crimp termination. The housing is constructed from aluminum alloy with an olive drab cadmium plating finish, providing environmental resistance and durability in harsh conditions. This component utilizes a quick disconnect push-pull coupling mechanism for rapid mating and unmating operations. It is rated for operation within a temperature range of -65°C to 200°C. The connector supports high-density interconnect applications requiring reliable signal transmission in demanding environments.
